Aalborg Portland orders two calciners from A Tec
08 March 2017Denmark: Aalborg Portland has awarded A Tec a contract to upgrade its Cement Kiln 87 in Aalborg. It has ordered two calciners for its 4500t/day semi-dry kiln system that was commissioned in 1988. The calciners will be designed and delivered during the kiln’s annual stop in February and March 2017. Commissioning is planned for the spring of 2017. The upgrades are intended to increase production of Ordinary Portland Cement on the line.
A Tec intends to adapt the flow pattern of the calciner system in a way to improve the operational behaviour of the system. The design will be configured for the usage of 100% solid alternative fuels with low emissions. Additionally, the number of kiln stops due fall through cyclone blockages should be reduced. A Tec will conduct the engineering, supply the equipment and will be responsible for errection and documentation.
The new calciner system will be equipped with the A Tec Post Combustion Chamber (PCC) for the optimised mixture of fuels and combustion air in the end section of the calciner. The PCC was specially developed for the achievement of complete combustion of alternative fuels at high substitution rates.
South Korea: SsangYong Cement has awarded a contract to Claudius Peters Projects for the supply of a grate cooler modification. The existing cooler at the Donghae cement plant will be upgraded by with an ETA 5th generation clinker cooler system. It consists of a fixed inlet, the High Efficiency module (HEM) and a moving floor ETA technology. It is designed for a stable production at 7600t/day.
SsangYong cement was established in 1962 and operates the world’s largest cement plant in Donghae with a capacity of 11.5Mt/yr of clinker. It employs around 400 workers.
South Korea: Voith has reported on a contract to engineer and install a belt conveyor drive and controller system for SsangYong Cement’s Donghae plant. Changes made by the engineering firm to two belt conveyors from the main limestone quarry to the plant managed to double the production of the quarry.
The engineering company installed new drive trains on the longer 12.8km SB500 belt conveyor, one of the longest single conveyors in the world. The installed power is now 2 x 1.2MW at the head and 1 x 1.2MW at the tail of the conveyor. The existing drives from the longer conveyor were used to double the number of drive trains on the shorter 2km SB200 conveyor. The new configuration of the SB200 drive system consists of 4 x 600kW installed power at the head equipped with new gearboxes. A Voith TurboBelt DriveControl system was also installed to reduce the start-up time of the longer conveyor by half, from originally over 10 minutes. The system includes active-load sharing, belt conveyor control, slip detection and remote service capability. It is also expected to extend the belt lifetime by reducing the mechanical stress as well as the dynamic impacts.
“Due to this retrofit project, we were able to reduce the working hours of plant workers, achieved cost savings, and a flexible operation is now possible. Thanks to Voith’s technical support and efforts, the plant will enjoy sustainable operations providing value to its community, its owner, and the employees,” said Dukgi Lee, General Manager of the plant.
US: The US Customs and Border Protection plans to start awarding contracts by mid-April 2017 for a proposed border wall with Mexico. The agency says it will request bids on or around 6 March 2017 and that companies would have to submit ‘concept papers’ to design and build prototypes by 10 March 2017, according to the Associated Press. Finalists must then submit offers with their proposed costs by 24 March 2017. No details on where construction will start or how much it will be cost have been released.
Estimates for the cost of a 2000-mile border wall vary significantly. The Government Accountability Office estimates it would cost on average US$6.5m/mile for a pedestrian fence and US$1.8m/mile for vehicle barriers. However, an internal Homeland Security Department report prepared for department secretary John Kelly places the bill at about US$21m according to an anonymous source quoted by the Associated Press. It proposes that existing barriers built during the George W Bush administration be extended first in stages.
The cost of the wall will depend on the height, materials and other specifications of the project. Granite Construction, Vulcan Materials and Martin Marietta Materials are all likely to be potential bidders and Mexico’s Cemex is also likely to benefit from any increase in demand for construction materials in the region.
LafargeHolcim Kujawy cement plant in Poland to have chlorine bypass system upgraded by A Tec
17 February 2017Poland: LafargeHolcim has awarded a contract to A Tec to upgrade the chlorine bypass system at its Kujawy cement plant. A Tec will upgrade its existing Reduchlor bypass system to increase the rate to 10% from 5%. The upgrade will retain the system’s existing bypass filter and filter fan. The project will be commissioned in spring of 2017.
A Tec’s Reduchlor bypass system consists of a take-off chamber above the kiln inlet, specifically designed for each installation, and a specially designed quenching chamber, to which the chlorine condenses on and adheres to fine dust particles. After this condensation process the chlorine-enriched material is collected in a filter.
Pioneer Cement signs deal with Chengdu Design & Research to build new line at Chenki
10 February 2017Pakistan: Pioneer Cement has signed contracts with Chengdu Design & Research Institute of Building Materials Industry (CDI) to build a new 8000t/day clinker production line at its cement plant in Chenki, District Khusshab in Punjab. The order also includes a 12MW waste heat recovery unit and a captive 24MW coal power plant. No value for the order has been disclosed.
Government auditor criticises Jammu and Kashmir Cements for allowing contractor to abandon cement plant project
30 January 2017India: The Comptroller and Auditor General of India (CAG) has criticised the management of Jammu and Kashmir Cements for allowing a contractor to abandon a contract to upgrade a cement plant without incurring a financial penalty. The subsequent reduction in production between 2010 and 2014 led the plant to loose an estimated US$5.6m, according to a report seen by the Early Times newspaper.
Engineering contactor Promac Engineering Industries was originally awarded a US$10.5m contact to upgrade the plant in 2005. Work started in June 2006 but the contractor left the site in 2010. The original terms of the agreement required Promac to complete the upgrade within 26 months and pay a financial penalty if the plant’s production capacity fell, if any increase in power or fuel consumption occurred or if the contract was delayed. Additionally, a packing plant that was built as part of the contract remained unused until 2015.
ThyssenKrupp to build cement plant in Algeria
25 January 2017Algeria: ThyssenKrupp’s Industrial Solutions has been awarded a contract by Société des Ciments de Sigus, part of Groupe Industriel des Ciments d’Algérie (GICA), to build a cement plant at Sigus, in the Wilaya of Oum El Bouaghi, near Constantine. The plant will have a clinker production capacity of 6000t/day. Operation is planned to start in early 2019. No exact value for the order was disclosed but it was placed above US$100m.
GICA has launched several projects to increase its cement production capacity from 12Mt/yr to 20Mt/yr by 2019. ThyssenKrupp previously received an order from GICA in 2013 to build a 6000t/day cement plant.
